Two-Year Outcomes and Predictors of Target Lesion Revascularization for Non-Left Main Coronary Bifurcation Lesions Following Two-Stent Strategy With 2nd-Generation Drug-Eluting Stents

ABSTRACT


BACKGROUND - Data on outcomes of non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation drug-eluting stents (DES) are insufficient. Methods and Results: The 2-year outcomes and predictors of target lesion revascularization (TLR) in 356 patients with 364 non-left main coronary bifurcation lesions treated with the 2-stent strategy using 2nd-generation DES were retrospectively evaluated. The primary outcome measure was defined as TLR. The median follow-up duration was 3.6 years (interquartile range, 2.7-4.9 years). A 2-year clinical follow-up was achieved in 99.2%. The 2-year cumulative incidence of TLR was 9.2%. Multiple stents implanted in either the main branch (adjusted odds ratio [OR] 3.01; 95% confidence interval [CI]: 1.37-6.62; P=0.006) or the side branch (adjusted OR 4.55; 95% CI: 1.99-10.4; P<0.001) and the culprit in the left anterior descending artery and its diagonal branch (adjusted OR 0.33; 95% CI: 0.15-0.75: P=0.008) were independent predictors of TLR within 2 years.


CONCLUSIONS - The 2-year outcomes for the 2-stent strategy using 2nd-generation DES in non-left main coronary bifurcation lesions were acceptable. Coronary bifurcation location in the left anterior descending artery and its diagonal branch is protective against TLR, whereas multiple stents implanted in either the main branch or the side branch was associated with TLR.
